Diesel Injector Roj Injector 095000-6520 095000-6521 Denso Injector rau Hino, Toyota Dyna, Toyoace

Lub injector koob valve coupler yog ua los ntawm GCr9 los yog GCfls pob bearing hlau. Tom qab sib tsoo sib tsoo, qhov sib txawv ntawm lub koob valve thiab lub koob valve lub cev tsuas yog 0.001-0.003, nnl, thiab qhov ua haujlwm ntawm qhov roughness yog Rao.16-0.32 Pin n, lub roundness ntawm rab koob valve thiab cylindrical nto nyob rau hauv lub koob lub rooj zaum qhov thiab qhov ncaj ntawm lub axis tsis ntau tshaj 0.001mnl. Nrog rau qhov zoo sib xws, yog tias koj tsis them sai sai rau kev ntxuav ntawm qhov chaw, nws yooj yim heev ua rau cov tshuaj tua kab mob, cov roj los yog khiav tawm ntawm lub tog raj kheej.
1. Cov roj diesel ntxiv rau lub cav roj tank yuav tsum tau precipitated thiab lim rau ntau tshaj 48 teev; tsis tu ncua ntxuav lossis hloov cov lim dej diesel.
2. Ua ntej disassembly, tshem cov roj rau ntawm qhov chaw ntawm lub injector. Cov koob txhaj tshuaj tshem tawm yuav tsum tau muab ntxuav hauv cov roj diesel huv (nws yog qhov zoo tshaj plaws tsis txhob ntxuav nws hauv cov tshuaj ntxuav hlau, thiaj li tiv thaiv cov dej noo hauv cov kua ntxuav los ntawm kev ua kom lub koob valve coupler puas ntsoog stains). Yog hais tias lub qhov nozzle ntawm lub koob valve lub cev yog thaiv los ntawm cov pa roj carbon deposits, nws yuav tsum tau soaked nyob rau hauv lub cav roj. 10 ~ 20h, tom qab cov pa roj carbon deposits softened, siv nyias xyoob sticks los yog burning koob los ntxuav nws; Yog hais tias lub koob valve yog daig nyob rau hauv lub koob valve lub cev thiab tsis tuaj yeem muab tshem tawm los ntawm txhais tes, nws tuaj yeem tsau rau hauv cov roj kub kub uas siv tau rau ib lub sijhawm, thiab tom qab ntawd muab qhwv nrog cov pliers Clamp daim ntaub thiab tshem tawm; rau lub koob valve khub niam txiv uas hnyav ablated thiab daig (xiav rau ntawm qhov chaw), vim qhov kub thiab txias annealing, hardness thiab hnav tsis kam txo, thiab yuav tsum tau hloov.
